我正在用 symfony2 做一些 PHPUnit 测试。我在一项特定测试中遇到问题。
我正在测试我类(class)之一的回应,当然一个回应是对的,一个是错的。我有一个我的数据库的模拟,并且我有一个来 self 的 databaseRepository 的方法的 stub 。
问题是,在一个测试中,我对具有有效数组的方法进行了 stub ,在第二个测试中,我只想查询无效的 null。
我的数据库模拟:
//Setting up mock of database repository class
$this->db = $this->getMockBuilder('DatabaseRepository')
->disableOriginalConstructor()
->getMock();
$this->db->expects($this->any())
->method('getRecord')
->will($this->returnValue(self::$registrationRecord));
$this->db->expects($this->any())
->method('getRecord')
->willReturn(null);
所以我试图有两个不同的期望,但是这显然是行不通的......是否有可能有一个 stub 方法有两个不同的返回..?
测试 1:
<?php
class UnsubscribeRegistrationTemplateTest extends \PHPUnit_Framework_TestCase
{
/**
* @var UnsubscribeRegistrationTemplate
*/
protected $object;
/**
* @var ValidationClass
*/
public $validate;
/**
* @var DatabaseRepository
*/
public $db;
//Database Record Mock
public static $registrationRecord = array
(
'rowid' => '96',
'unsubscription' => 'N',
'updated' => 'BB'
);
/**
*
*/
protected function setUp()
{
//Setting up mock of validation class
$this->validate = $this->getMockBuilder('ValidationClass')
->disableOriginalConstructor()
->getMock();
$this->validate->expects($this->any())
->method('validateInput')
->willReturn(true);
//Setting up mock of database repository class
$this->db = $this->getMockBuilder('DatabaseRepository')
->disableOriginalConstructor()
->getMock();
$this->db->expects($this->any())
->method('getRegistrationRecord')
->will($this->returnValue(self::$registrationRecord));
$this->db->expects($this->any())
->method('getRegistrationRecord')
->will($this->returnValue(null));
$this->db->expects($this->any())
->method('setPreRegistrationEnquiryUnsubscriptionEnabled')
->willReturn(true);
$this->object = $this->createUnsubscribeRegistrationTemplateInstance();
}
/**
* @return UnsubscribeRegistrationTemplate
*
*/
public function createUnsubscribeRegistrationTemplateInstance()
{
//initialize Unsubscribe Registration Template
return new UnsubscribeRegistrationTemplate
(
$this->validate,
$this->db
);
}
/**
* @param array $mapping
* @return Request
*/
public function createRequest(array $mapping)
{
$request = new Request();
foreach ( $mapping as $k =>$v)
{
$request->query->set($k, $v);
}
return $request;
}
/**
*
*/
public function testUnsubscribeRegistrationTemplateValidResponse()
{
$request = $this->createRequest(array(
'registration_id' => '96',
'source_channel' => 'BB'
));
$response = new Response(
true,
'Unsubscription successful'
);
$this->assertEquals($response, $this->object->create($request));
}
/**
*
*/
public function testUnsubscribeRegistrationTemplateEmptyResponse()
{
$request = $this->createRequest(array(
'registration_id' => '96',
'source_channel' => 'BB'
));
$response = new Response(
false,
'Registration Record Not Found.'
);
$this->assertEquals($response, $this->object->create($request));
}
/**
*
*/
public function testIsAlreadyRegisteredValidResponse()
{
//Testing record is already unsubscribed
$registrationRecord = array(
'unsubscription_enabled' => 'Y'
);
$this->assertTrue($this->object->isAlreadyUnsubscribed($registrationRecord));
}
/**
*
*/
public function testIsAlreadyRegisteredInValidResponse()
{
//Testing record not unsubscribed
$registrationRecord = array(
'unsubscription_enabled' => 'N'
);
$this->assertFalse($this->object->isAlreadyUnsubscribed($registrationRecord));
}
/**
*
*/
protected function tearDown()
{
unset($this->object);
}
}
最佳答案
您可以通过多种方式做到这一点。
这里有两种方式可能适合您的需求。
1 - 将 getRecord() 期望移至测试
/**
* @test
*/
public function ifTrue()
{
$this->db->expects($this->once())
->method('getRecord')
->will($this->returnValue(self::$registrationRecord));
$request = $this->createRequest(array(
'id' => '10',
'code' => 'BB'
));
$response = new Response(
true,
'successful'
);
$this->assertEquals($response, $this->object->create($request));
}
/**
* @test
*/
public function ifFalse()
{
$this->db->expects($this->once())
->method('getRecord')
->willReturn(null);
$request = $this->createRequest(array(
'id' => '10',
'code' => 'BB'
));
$response = new Response(
false,
'Record Not Found.'
);
$this->assertEquals($response, $this->object->create($request));
}
如您所见,有很多重复项,所以让我们使用 dataprovider .
2 - 使用@dataProvider
protected function getDataForTest()
{
return array(
array(self::$registrationRecord, true, 'successful'),
array(null, false, 'Record Not Found.')
);
}
/**
* @dataProvider getDataForTest
* @test
*/
public function ifTrue($getRecordValue, $bool, $message)
{
$this->db->expects($this->once())
->method('getRecord')
->will($this->returnValue($getRecordValue);
$request = $this->createRequest(array(
'id' => '10',
'code' => 'BB'
));
$response = new Response(
$bool,
$message
);
$this->assertEquals($response, $this->object->create($request));
}
使用@dataProvider,您可以使用任意数量的值来测试所有情况。
